  "targetTypeVersion": 3
}

​
Response

Returns arrays of successfully migrated and failed content IDs. 
{
  "migrated": ["cont123", "cont124"],
  "failed": [
    {
      "id": "cont125",
      "error": {
        "code": "VALIDATION_FAILED",
        "message": "Content does not match target schema"
      }
    }
  ]
}
Bulk migration is atomic per content item. Failures do not rollback successful migrations. Review the failed array to identify and fix issues.
